摘要：

N-butylamine and n-octylamine were added to the preparation of lanthanum phosphate from lanthanum nitrate and phosphoric acid solutions to obtain phosphate materials that had large specific surface area. The mixing solution of water and ethanol was used to solve these amines. The additional effects of amines and the mixing ratio of solvent were studied on the chemical composition, powder properties, and adsorption of basic stinking gas. Rhabdophane-type lanthanum phosphate was obtained in spite of the changes of preparation conditions. Specific surface area of lanthanum phosphate prepared in this work became over 10 times as large as that of standard phosphate.
